cariocas exude a confidence in almost every situation - this self-assurance and clarity of purpose is a part of their cultural identity, an important part of the way that they assert themselves and their interests.

it is not a facet of arrogance, but instead a product of the deep-rooted optimism which guides them through their lives - they have an inner belief that things will, ultimately, turn out okay, and situations will get resolved one way or another.

it is not in the nature of cariocas to ruminate on the past or catastrophize about the future, it is simple to be and do in the present - a painter who arrives to paint one's living room will offer to fix the sink with absolutely no plumbing knowledge, fuelled by an endearing combination of belief in himself and the desire to help, both of which are fundamental carioca attributes.
